MATTRESS on THE LIKE.

.Application filed January 19, 1921. Serial No. 438,478.

To all whom it may; concern:

Be it known that I, FRED BAUER, a citizen of the United States, residingat Milwaukee, county of Milwaukee, and State of Wisconsin, have inventednew ;and;useful Improvements in Mattresses or the like, of which thefollowing; is a specification.

This invention relates to mattresses or the like. It is particularlydirected to an im proved means of securing the springs of resilientmattresses and cushions in position.

- Objects of this invention are toprovide a novel means for securing thespringsto the covers of resilient mattresses or cushions and to providenovel means of securing adjacent springs to each other.

Further objects are to provide for simul taneouslysecuring adjacentsprings to each other and to the covering; to provide means for securingsuch springs by widely spaced portions of the same securing member; to

provide a novel means of distributing the strain placed upon thesecuring means; and to so organize the'securing means'that any slackresulting from the manipulation thereof may be taken up at eachsuccessive spring; and to generally simplify the construction ofresilient cushionssuch as mattresses, upholstery and the like. C q

Embodiments of the invention are shown j in the accompanying-drawings,in which:

Fig. 1 is a partial plan view of a mattress embodying one form of theinvention with parts of the covering broken away to illustrate detailsof the construction.

Fig. 2 is a fragmentary side elevation the structure shown in Fig.1.

Fig. 3 is a view corresponding to Fig. 1 showing a further form of theinvention. Fig. 4 is an'enlarged detail of the final knot for eachspring.

Fig. 5 is an enlarged detail of one of the intermediate knots.

Thisinvention relates to either a mattress such as shown in Fig. 1 oranautomobile cushion such as shown in Fig. 3. It is to be noted that asa rule lighter springs are used in mattress construction than inautomobile seats orbthe'r similar resilient cushions. Where heaviersprings aroused,

additional securing means are usually em-' ployed as illustrated in Fig.3. V r

In practicing this invention, the springs are arranged in a series ofrows as illustrat-j ed in either'Fig. 1 or Fig. 3 and a covering ofburlap or similar material is spread over the upper surface thereof withthe edges hanging down upon the sides of the springs. This covering isthen tucked in between each of the springs as indicated at 1 in Fig. 2,thereby spacing adjacent portions of the terminal convolutions of thesprings apart by the interposed double thickness of fabric. After thecovering has been thus arranged, the stitching is begun at one corner ofthe mattress and continued around the four sides thereof across theupper ends of the outer rows of the springs. Thereafter, thestitchingmay continue roughly as a spiral or else back and forth acrossthe length or the width of the mattress. The stitchingis begun bypassing the needle thru the fabric and under the outer portion of theupper convolution of, a corner coil and is thereafter knotted. From thispoint, the stitching extends around a rectangle about the upper end ofthis coil and at each place where it is atcoil. The final knot, however,is formed as, in Fig. 4 by passing the securing cord down-" wardly thruthe burlap about both terminal convolutions and under the adjacentstrands 7 of thesecu'ring coil for the first spring. .It

will thus be seenthat this final knot serves as a meansto take up anyslack resulting in the securing cord of the first 'coil. This method ofstitchin g is continued around the entire mattress as stated above.

After one covering is in place, the partially formed mattress is turnedupside down and the other covering is positioned and stitched .aswas thefirst one. After these two coverings are in position, their side"margins are stitched together, for example.

by folding them'inwardly asindicated 7 2 in Fig. 2, and running a lineof stitching 3, such for evample, as ordinary machine stitching,completelyaround' the sides of a mattress. I r

Fig. 1 shows "one form of the invention and the securing of one or moresprings will be described in detail. The burlap covering is indicated ate and adjacent springs at 5, 6, 2' and S. The securing cord 9 is knottedabout adjacent portions of the terminal conrelations of the springs 5donwardly thru the burlap within each of the convolutions and thru thefolded portion 1 of such covering. After the knot, similar to thatindicated in Fig. 5 has been formed, the cord 1.0 is passedalong-oneside of a rectangle thru the burlap -and about the outerportionv of the terminal convolution ,posi'tioned injtheir,properrelation to each ner. T'he cord 11 .is now passed. from, this. i

of the spring 6 and knotted in the same manpoint along the second sideof the rectangle thru .the burlap andknotted about the terminalconvolutions of the springs .6 :and 7 passing thru the folded portion 1of thebur- *lap. Fromthis .point,.the cord 12..passes alon the thirdside of. the rectangle thru the burlapand .tl1e:folded portion thereof..about .the terminal .convolutions of the springst and 13, is knottedand passedback to the startingpoint' 1 1-. along the fourth side v ofthe rectangle, this length of cord being ,indicated at 1.5. Thisknot is,however, ,.l ornietl differently from the knots pre- 39 riously.described... It is, of course, to .be

understood thatthe portions. 9, 10, 11,112, 15, etc. ofthe cord areintegral, that. is to say, the cord runs continuously from the Istarting. point completely around the vmattress and acrossallsthe springterminal conj volutions'upon onesidezotthe mattress.

The 'last mentioned knot is illustrated. in Figgl and it will-benotedthat the securing cord 15,.along the 'last sideot. the square, is vthruithe burlap about the-terminal convolu-.

tionofthespring 6.; over the securing cord 10, under the securing cordsl6, 9 and '17 of thespringgfi, above the burlap covering, and

- either over or under the cord 15 of the spring 6. When this cord 18 isthentightened, it takes-upthe slack iuthe cords 16, 9=and l'T oi'thespring 5. V V

Frorn this :point, the cord- .18 extends diagonally: acrossQthe:terminal convolution of the springfi andisiknottedas indicated in Fig.5, downwardly thru the burlap, thru the "folded portion thereof,andupwardly so as to pass aboutthe terminal convolutions of the springs6 and 7. It .is now knotted as indicated at Fig. 5. andthe processisrepeated. It the mattress be considered as-made o'f'successiveconcentric closed series of springs. each series arranged in rectangles,the cord l8..passes diagonally across all of the springs except thecorner: springsofeach series. At the corner springs, the..=same method.or" stitching is employed except after and G passing thstitchingproceeds as described for the spring 6. g

In-assembling the springs prior to. the positioning of the firstcovering thereon they may conveniently be placed upon a series of pegscarried by a jig or templet to .hold them in proper.arrangement.lf'lowever, after the stitchingof the first covering has. beenIfinished, the --springs' are securely othen-and the covering: andspring forming the partiallyfinishe'd mattress'niay be turned upsidedown upon ,a, flatsurtaceand the second vcoveringaziplied and, secured.It is to be, noted'that by running a -linje or stitiching completelyaround the outer rows of springs that all otthe springs are more firmlypositioned and the subsequent. stitchingotv the. inner springs is. morereadily effected. V 9 This method may beadrantageously em ployedt'or'mattresses or resilient cushions ofanytype in, which springs formed ofme v.idium sized resilient w'ire are employed. However, when springs ofrelative-1yheavy 'WllG are employed, as torexample, in. auto-- mobile.cushions, additional 1 stitching may be made oventhis stitchinglalreadyjformed. Fig. 8 is fragmentary view or an auto- .mobile cushion :fformedof; relatively heavy. 109 springs 22, .23, 2s, etc. After the" burlapcovering has been properlyfpositioned and secured asfpreviously.desc'ribednby the first form of stitchingga second stitching ism-ade bypassing a cord 25"direct1y along onefrowg of springs. This cord 25 ,isknotted at 26 aboutithe terminal convolutions of springs 2ft .and 27,fpasses diagonally as indicated [at 28 across thecspring 24:, and isknotted 'asindicated at, 29 about the terminal corn, 1" volutions ofsprings 23 and 24,.the cord in each case, of course,,passing downwardlythru the burlap,1thrii the ffoldedportion; l,

,and.npwardl'y as is ob'viou'st'rom an in spection ot'iF gs. '2- and 3.This line 011,1 stitching continues until then argiirof thev mattress isreached. Atthis point. the knot 30 is formed-and the, cord is passed asindicated at 31 to the knot for thejspring 33. From this point,thecordpasses'as in- 1 .dioated at3 l along the next. row of springs. Thisprocess is repeatedfuntil thelen-tire rows of springs have been securedby this .transverse fllineofQstitching. Similar lonj gitudinallllines ofstitching as indicated at,,. 35 v aref formedand] pass longitudinally:along p'arallel. rows-of springs as indicated in .After onelsidei' .otheautomobile cushion 'or other resilient cu'shioif has been stitched asindicated in Fig. 3, the cushion is reversed and the processrepeatedupon the other side thereof. I

It will be noted that this additional series of transverse andlongitudinal stitching gives additional security against breakingstrains such as are often encountered inautomobile cushions. However,the first form of stitching also contributes to the ultimate strengthand secure positioning of the springs and cooperates with the transverseand lateral stitching just described to produce an extremely strong and.efiicient cushion. V

In addition to the forms of stitching shown in Figs. 1 and 3, thisinvention contemplates employing the reenforcing stitching such as shownat and 35, Fig. 3, alone. In this case. an additional line of stitchingwould be run completely around the mar-v ginal edges of the terminalconvolutions prior to the formation of the longitudinal and transversestitching such as indicated at 25 and 35. This marginal stitching wouldpass thru the burlap and be knotted about the outer portions of each ofthe terminal convolutions completely around the periphery of themattress.

It will be seen that a very simple method has been provided for securingadjacent springs to each other and to the fabric covering of resilientmattresses orsimilar articles. It will also be seen that the articleproduced hasvery desirable characteristics, such as a small number ofparts and equalization of strains in the connecting cord and a greatinlicrent strength thereby successively resisting displacement of itsvarious parts and stresses imposed thereon.

It will further be seen that in practicing this invention, the stitches,knots, andpeculiar relation thereof, produces a mattress of greatinherent rigidity and strength. The

final knot, following the stitching of each spring to the covers, takesup the slack in all of the cords passing across the top of that springand serves to tie the adjacent springs very tightly together. This isparticularly desirable in a mattress or cushion of this type. A mattressconstructed in this mannerv will stand alone without bowing over orotherwise folding. It is not necessary to provide an external orsurrounding frame.- work for a mattress made in this manner as itsinitial shape will be retained independently of any auxiliary supportingmeans.
